Title: Data recovery circuit
Inventor: TAKIGAMI HIROBUMI
IPC: G11B19/02
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To enhance a probability of reading data in a data area when a servo area where an readout is impossible is generated in a magnetic disk device of a data-surface servo system. SOLUTION: At the time a lower order circuit 2 reads out data stored in a magnetic disk, it transmits a servo mark signal when it detects a servo mark and also transmits a servo error signal when the read error of the servo mark is generated. A current servo interval counting circuit 5 counts the interval of servo areas based on the servo mark signal to transmit a current servo interval signal. A recovery signal is transmitted from a higher order circuit 1 in response to the servo error signal.  When a current circumferential position calculating circuit 6 receives the recovery signal, it calculates the position of the servo mark where a read error is generated based on a reference interval expressing the interval between the current servo interval signal and the servo area and generates a circumferential position signal by correcting detailed information expressing detailed positions of the servo area and a data area. The lower order circuit 2 performs the read operation of a magnetic disk at timing to be shown by the circumferential position signal.

Filed: 1980-09-27
Abstract: PURPOSE:To discriminate surely the signal transmission state under an intensive fading peculiar to mobile communication, by discriminating the level by a clock of a transmission speed higher than that of a digital signal and by discriminating  whether a signal exists or not on a basis of the count value of the frequency of this discrimination. CONSTITUTION:The signal which has the frequency shifted by the digital signal for control inputted to an antenna 1 is detected by a receiver 2, and the detection output is supplied to a clock circuit 4 and full-wave rectifying circuit 5 through an LPF3. The output of this circuit 5 is applied to a delay FF7 after having the waveform shaped by a comparing circuit 6. A clock for control synchronized with the digital signal is generated by the clock circuit 4 and is applied to the FF7 and an AND gate 8, and the output of the FF7 is applied to the gate 8. Then, the level is discriminated by the clock of a transmission speed higher than that of the waveform shaped digital signal, and the frequency of discrimination of level 1 is counted  for a prescribed time by a counting and discriminating circuit 9, and transmission of the signal is stopped when the count value is a prescribed value or less.

Abstract: PURPOSE:To improve combustibility, by providing a guide wall, turning intake, between an intake port and a recirculative port, in the case of an engine which has an intake recirculating passage allowing each cylinder to communicate and closes the recirculative port, opened to the cylinder in said passage, by an intake recirculating valve. CONSTITUTION:This intake device has an intake passage 3, supplying intake through an intake port 4 to each cylinder 2 of a multi cylinder engine, and an intake recirculating passage 7 permitting each cylinder 2 to communicate and recirculating a part of the intake, supplied to each cylinder 2, in a compression stroke. And the engine, closing a recirculative port 8 opened to each cylinder 2 in the intake recirculating passage 7 delaying from the close timing of the intake port 4, controls the ports 8 to be opened and closed by an intake recirculating valve 20.

Title: Magnetic recording and reproducing device
Inventor: TAKAHASHI TOORU
IPC: G11B15/02
Filed: 1983-07-25
Abstract: PURPOSE:To prevent the damage of a tape even in a sagged state in case the tape is set under a rapid traverse or rewinding mode at the time of application of a power supply by winding the sag of tape at a low speed, then transferring the operation to a stop mode. CONSTITUTION:A control circuit 11 starts its actuation as soon as a power supply is turned on. Then only a sensor 7 produces a detection signal, and a reel revolving signal for low speed is produced when a cam 1 is set in a rapid traverse mode. In this case, a take-up reel 14 is revolved at a low speed in the take- up direction of a tape 20. A sag part 20a is taken up by the reel 14. Then a supply reel 12 is pulled by the tape 20 and starts revolutions. Thus a frequency generating circuit 13 produces a signal FGS1, and the revolution of the reel 14 is stopped. Only a sensor 8 produces a detection signal to eliminate the tape sag through a similar process even in a rewind mode. Thus the damage of a tape is prevented.
